  | BM(Image<(Of <<'(Gray, Byte>)>>), Image<(Of <<'(Gray, Byte>)>>), Size, Size, Size, Boolean, Image<(Of <<'(Gray, Single>)>>), Image<(Of <<'(Gray, Single>)>>)) |
Calculates optical flow for overlapped blocks block_size.width * block_size.height pixels each, thus the velocity fields are smaller than the original images.
For every block in prev the functions tries to find a similar block in curr in some neighborhood of the original block or shifted by (velx(x0,y0),vely(x0,y0)) block as has been calculated by previous function call (if use_previous)
